Enemy Mine is a serious film actually — haven't seen it since I was a kid though. It's very, very moral, and not terribly good.
Hobo With a Shotgun wasn't really that good either.
@Cali I think / hope once the new Batman and the Avengers comes out comics movies die down for a while. Definitely a case of 'less is more' right now. I saw X-Men: First Class on a plane the other day, and although the triumvirate of McAvoy, Fassbinder and Bacon was quite fun, it isn't anywhere near as good as people have claimed to me.
So there are three films which basically underwhelmed me.
